Two identical nonconducting triangular plates each of area A carrying uniform positive charges +3q and -2q are kept parallel to each other by inserting three identical insulating rods between their corners as shown in the figure. Distance between the plates is much smaller than their linear dimensions. Assuming the assembly to be isolated from other bodies, find compressive forces developed in the rods
